'To ctZZ whom/1115 may concern:

Be it known that 1, JOHN F. MCGUIRE, a citizen of theUnitedStates,residing at Akron, in the county of Summit and State ofOhio,

I have invented a certain new and useful Improvement in WVire-OoveredHose, of which the following is a full, clear, and exact description,reference being bad to the accompanying drawings. a

Wire-covered hose is used very extensively for conveying compressed airor steam to various kinds of tools operated thereby and which areadapted to be moved to different points or into different positions, asthe condition may require. It has been found that in dragging the hosefrom place to place, as is necessary in shifting the tools from place toplace, there is a tendency for the wire covering the hose to becomecaught upon projections or debris over which it may be drawn, and thistendency not only is a disadvantage to the manipulation of such hose inindustrial operations, but-if any considerable force be exerted upon thehose when it has been caught in this manner there is considerable dangerof shifting the coils of thewire bodily upon the hose. Round wire hasbeen used for covering hose; but this form is peculiarly attended withthe disadvantages mentioned and involves also another incidental defect.If it is wound tightly enough upon the hose to prevent its beingdisturbed with relation to the hose, it will then cut into the hose whenthe same is subjected to the vary considerable pressure often obtainedin practice.

The object of my invention is to meet and remedy this defect. This I doin two waysby constructing the enveloping wire of a form not adapted tobe readily engaged or caught by projections, &c.., and by providing thewire with such a form on its inner side that it will be with difficultydisturbed or dislo cated when once it has been placed about the hose. Inother words, by a peculiar construc- 4 5 tion and form of thecovering-wire, to be more fully described hereinafter, I minimize theprobability of an opportunity occurring for dislocating the wirecovering, and I provide means for preventingor resisting such a dis- 50location should such an opportunity occur. Flat bands have been used asa covering, and

while bands of this form have the advantage of presenting-a wide'surfaceon the side toward the hose they are, if possible, even more poorlyadapted to the operations incident to 5 5 the work, as they aremostreadily caught by projections and debris.

The invention consists in the construction and combination of partshereinafter described, and definitely set forth in the claims.

In the drawings. Figure l is a side elevation of a section ofwire-covered hose embodying my invention. Fig. 2 is a side elevation inwhich a part of the wire and a part of the hose are in section. Fig. 3is a sectional plan View of said hose. Fig. 4 is a transverse sectionalView of the wire in its best form.

Referringto the parts by letters, A represents the hose, and B a metalstrip or wire which is wound spirally upon the same. This wire ispreferably substantially half-round in transverse section, wherefore thesurface thereof which'lies against the hose is substantially flat andthe outer surface is inclined in both directions, so that both edgesmeet the hose in a thin edge. When this hose is being dragged along,these inclined edges will ride over any obstaclesin their path insteadof being caughtv thereby. They will likewise ride over the dirt insteadof catching it, 30 therefore requiring that it be dragged along with thehose. The broad fiat surfaces engaging with the surface of the hose willprevent the wire from cutting into the hose and also because of the widebearing-surface will in large measure prevent the-wire from beingshiftedupon the hose. This last result, however, is attained withgreater completeness by providing on the inner fiat face of said wire arib b, which may be continuous, 0 as shown, or it may be broken .orintermittent, as is also shown. This rib projects only a very shortdistance, and while it'will be forced into the-rubber a distancesubstantially equal to its height any greater penetration is preventedby the broad fiat surfaces of the inner face of said wire.

Although, as heretofore stated, this sort of hose finds its greatestfield of usefulness in connection with the transmission of com- I00pressed air and steam from place to place, it is nevertheless capable ofbeing used and is to some extent used for conveying water or liquids.

Having described my invention, I claim 1. A rubber hose combined with awire wound spirally thereabout, said Wire having a flat face adapted tocontact with the outer surface of said hose and a small projecting beadcarried by said flat face and pressed into the wall. of said hose,substantially as and for the purpose specified.

2. A rubber hose, combined with a wire, wound spirally about the samehaving an inner flat face and an outer surface whose edges are inclined,and having, projecting from its inner fiat face, a rib, substantially asand for the purpose specified.

3. A rubber hose combined with a wire wrapped helicallyt-hereabout, saidWire hav ing a flat face adapted to contact with the outer wall of saidhose and having a bead located centrally of said flat face and extendingcontinuously therewith, said bead being pressed into the outer wall ofsaid hose, and said flat faces forming means to prevent the wire fromcutting through the hose, substantially as and for the purposespecified.

4. The combination of a rubber hose, and a substantially half-round wirewound spirally upon the same with its fiat face lying against saidh0se,and having projecting from its inner flat face a rib, substantiallyas and for the purpose specified.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.

JOHN F. MCGUIRE.
